mrsoulsatisfaction Posted January 10, 2011 Share Posted January 10, 2011 hi. i have a pair of kp-3002 that i am running off my qsc rmx 1450 amp and running it all thru a dj mixer. one of the speakers sounds blown as far as i know to call it. i get hi-s but now lows...well...VERY weak lows. so weak that you can barely hear it at all. i check that it wasnt just a problem with one of the channels or 1/4 inch plugs and switche each wire and plug to test them all. it is a problem in the speaker. so as to the advise on this thread i opend her up and checked all the wires and connecters...they seem to be fine. i also examined the base speaker and it seems to be fine too...no holes or tears. anymore help? i bought all three pieces for 300 from a store that was closing down. thanks for the help fellas. patrick ps...yes...that is my actual van. pps any help with technical terms that i am not naming correctly please correct me Quote Link to comment Share on other sites More sharing options...
Guest " " Posted January 10, 2011 Share Posted January 10, 2011 your not going to get a lot of lows out of them. they are designed to be used with a pair of sub's. by themselves, they are -10db down at 40hz. which means you need to add 10db of bass to them just to make them flat. Then from there, if you want bass, add more db's. problem is that adding db's for bass will quickly use up the speakers power handling. you are better off using the correct sub. see attached.

mrsoulsatisfaction Posted January 10, 2011 Author Share Posted January 10, 2011 that is helpful. from what i read so far it seems that everyone who has a pair of 3002 has the 4000 sub-woofer. i am very happy to go that way...now i just have to find a pair. BUT...the one speaker sounds horrible. i get just about NOTHING from the one speaker. i am so desperate and obsessed to figure out why it isnt working that i am about to open the other one and attach that 15inch to the one that isnt working to see whats up. any ideas? speaking of proper amping what do you think about running them off the qsc? will it run/sound well when i do find 4000? do i need to get a pair to run the crossover? that seems like a lot of questions so far so ill start with that. thanks again for the help. by the way...i mostly run my technics turntables off this system. my next big purchase will be a audiophile needle...need to research that. my gf runs her ipod of the mixer but i am a vinyl only man.

djk Posted January 10, 2011 Share Posted January 10, 2011 Buy a cone kit for the blown K-48 woofer, it should cost less than $100 (with labor) to repair. Quote Link to comment Share on other sites More sharing options...
mrsoulsatisfaction Posted January 10, 2011 Author Share Posted January 10, 2011 before throwing money at it i am going to tweak around a little more. i need peace of mind that its not a blown woofer. upon inspection it looks like it is perfectly fine. no ripes or dents or blemish of ANY kind. ill let you know how it goes when i swap out the woofer with the one i know works. wish me luck...im going in...

mrsoulsatisfaction Posted January 11, 2011 Author Share Posted January 11, 2011 so...it is not the woofer. i swapped the known working woofer with the one that wasnt working. when i put the woofer that "wasnt working" one the cab that was working it worked fine. what does this tell me? and i have also discovered that the speakers only sound good when the i turn the volume up. at a low volume i cant hear my mids or lows well at all and the hi 's sound like its coming out of a tin can. any solutions? thanks fellas.

djk Posted January 12, 2011 Share Posted January 12, 2011 Well it's good that you don't need a re-cone. Something in the input cup, crossover or wiring must be acting up. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted January 12, 2011 Share Posted January 12, 2011 pull the stupid locking 1/4" connector and substitute and Neutrik NL4 female socket, fits the exact same hole in the input cup. Quote Link to comment Share on other sites More sharing options...
